Grundle days

The Grundle is the narrow area between a man's ball-sack and his anus.

The "Grundle Days" are those few days which fall between the end of Christmas Day and the morning of New Year's Eve.

What are you doing with the Grundle Days this year?

Nothing.

Me too.

grundlesnaps

Crystally, clinging bits of sweat and various fluids that form on the pubic hairs. Differentiated from dingleberry in location and composition.
May be used as an insult or medical complaint.

Nothing is as aggravating as losing a ball-hair to a persistant grundlesnap.

Grundlelicious

Awesome, delightful, remarkable. As tasty as a grundle.

Jon's Jr. Bacon Cheeseburger was grundlelicious, but it sure could have used some mayonnaise.

grundlefresh

A freshness only comparable to the same wonderful taste and smell as the grundle region located between your scrot and chocolate starfish.

Guy 1: Man, every time that girl comes back from lunch she has such wonderful grundlefresh breath.

Guy 2: Dude, thats because shes blowing the boss in the hotel across the street.

Guy 1: Ah, that makes sense!
